Guisheng
Materials
RTV silicone gasket makers, dealcoholized-cure electronic sealants and thermal grease from Huadu, Guangzhou — registered 2022, registry-matched, scope disclosed as sales/R&D.
Gasket, seal, thermals.
RTV Silicone Gasket Maker
High-temperature RTV silicone gasket maker for formed-in-place gaskets — the auto-parts and industrial sealing staple, and the company’s first listed line.
One-Part Electronic RTV Sealant
One-component dealcoholized-cure RTV silicone sealant for electronics assembly — non-corrosive cure chemistry for sensitive components.
Thermal Grease
Thermal grease / thermal compound for heat-sink interfaces in electronics — the company’s thermal-management line.
Low MOQ to start, paperwork to confirm.
Three Product Lines
RTV silicone gasket maker for formed-in-place, high-temperature sealing; one-part dealcoholized-cure RTV sealant for electronics; and thermal grease for heat-sink interfaces — a focused gasket-seal-thermals range.
Registered & Traced
Registered April 2022 with RMB 1 million capital, originally in Foshan as Foshan Sisheng New Materials, later renamed and re-registered in Huadu, Guangzhou (registry record). Name, credit code, status and registered address all matched the registry in August 2026.
Low-MOQ Entry
Stated MOQ is just 50 pieces, with standard samples in 3–4 days and custom samples in about 5 — a low-risk way to test fit before committing to a program. Production runs are stated at about 15 days for small lots and 20–30 days for regular orders.
Customization on the Table
The application lists wholesale, brand, OEM/ODM and project buyers as target customers, with custom sampling offered — formulation, packaging and private-label requests are scoped at inquiry.
Stated Target Markets
Southeast Asia (Malaysia, Thailand, Indonesia, Vietnam), the Middle East (UAE, Saudi Arabia) and South America — markets where RTV gasket maker and thermal materials move through auto-parts, electronics and hardware channels.
Compliance Homework
For chemical imports, the paperwork is the product: ask for the TDS and SDS/MSDS per SKU, plus any third-party test reports your market requires, and confirm which entity issues them. This profile claims no certificates — none were provided at review.
Registration you can check — and what is still open.
Read this profile as a disclosure document. Verified: the registration itself — name, credit code, active status and registered address all matched the Chinese corporate registry in August 2026, and the 2022 Foshan registration under the company’s former name traces to the same entity. Disclosed as open: the registered scope covers sales and R&D with no manufacturing clause, so the producing entity must be named and documented before you order; the scope also carries no import/export clause, so confirm the export arrangement at inquiry; and a quality-management certificate listed on the application was not sighted at review, so this profile claims none. ChinaMakersHub does not restate a supplier’s certificate validity on its behalf — we tell you what to ask for.
A Guangzhou sealants supplier with a Foshan paper trail, disclosed as it is.
Guisheng Materials trades as Guangzhou Guisheng New Materials Co., Ltd. (广州市硅晟新材料有限公司), a company incorporated in April 2022 in Foshan as Foshan Sisheng New Materials and later renamed and re-registered at a factory-unit address in Tanbu, Huadu, Guangzhou, with RMB 1 million registered capital. ChinaMakersHub matched the company name, credit code, registration status and registered address against the Chinese corporate registry in August 2026; all matched.
The range is three product lines: RTV silicone gasket maker for high-temperature formed-in-place sealing, one-part dealcoholized-cure RTV silicone sealant for electronics, and thermal grease for heat-sink interfaces. Stated commercial terms are unusually accessible: a 50-piece MOQ, standard samples in 3–4 days, custom samples in about 5 days, and production in about 15 days for small runs or 20–30 days for regular orders. Stated target customers are wholesale, brand, OEM/ODM and project buyers; stated target markets are Southeast Asia, the Middle East and South America.
Three things are open, and they stay open on this profile until documents say otherwise. First, the registered scope covers sales and R&D of new materials with no manufacturing clause, and the industry classification is wholesale — the producing entity behind the products was not disclosed at review and must be named and licensed before any order. Second, the scope carries no import/export clause — confirm at inquiry whether export runs through an agent or a scope amendment, and whose name appears on customs documents. Third, the quality-management certificate listed on the application was not sighted at review, so this profile claims none. Registry data also shows a minimal social-insurance headcount — confirm real staffing and capacity with a live video walkthrough before scheduling a program. Contact routes through ChinaMakersHub; direct details are exchanged after first inquiry.

Frequently Asked Questions
What does Guisheng Materials supply?
Three product lines: RTV silicone gasket maker (high-temperature, formed-in-place gaskets), one-part dealcoholized-cure RTV silicone sealant for electronics, and thermal grease (heat-sink compound). Technical data sheets, packaging options and customization are shared at inquiry.
Is Guisheng a factory or a trading company?
The registry reads trade, not manufacture: the registered scope covers sales of non-metallic mineral products, rubber goods, engineering plastics and synthetic resins, electronics and synthetic materials, plus new-materials R&D — with no manufacturing clause, and the industry classification is wholesale. The registered address is a factory-unit address in Tanbu, Huadu. The producing entity behind the products was not disclosed at review — confirm who manufactures, under what licence, before you order.
Can Guisheng export directly?
The registered scope does not include an import/export clause, so direct self-operated export is not supported by the registry record — export would run through an agent or require a scope amendment. Confirm the export arrangement (and who appears on the customs documents) during inquiry.
What certifications does Guisheng hold?
The onboarding application listed a quality-management system certificate, but no certificate document was provided at review, so this profile claims none. What is on file: the registration itself (name, credit code, status and registered address all matched the Chinese corporate registry in August 2026). For any certificate or test report you are shown later, check the issuing body, the holder name and the validity date on the document itself.
What are the MOQ, sampling and lead times?
The company’s stated terms: MOQ 50 pieces, standard samples in 3–4 days, custom samples in about 5 days, production in about 15 days for small runs and 20–30 days for regular orders. These are the company’s own figures — confirm current pricing and lead time through ChinaMakersHub when you send your specification.
What should I check before importing sealants and thermal grease?
Two dossiers matter for this category: technical (TDS with viscosity, cure type, temperature range, thermal conductivity for the grease) and compliance (SDS/MSDS plus any third-party test reports your market requires for chemical imports). Ask for both with your first inquiry, and confirm which entity issues them.
