Frequently Asked Questions About CHEMPU Neutral Sealants
- What is a neutral sealant? A neutral sealant, such as neutral silicone sealant, cures without releasing acids, making it ideal for sensitive substrates like glass, metal, and stone. It offers excellent adhesion and long-term durability in both interior and exterior applications.
- What is the difference between neutral sealant and acetoxy sealant? Unlike acetoxy sealants that release acetic acid during curing (which may corrode some metals), neutral sealants are non-corrosive and compatible with a wider range of construction materials.
- What certifications does CHEMPU offer? CHEMPU’s sealants are compliant with ISO, ASTM, and EN standards. Specialized products (e.g., IGU sealant, fire-resistant sealant) carry additional certifications as required for safety and energy efficiency.
- How can I order CHEMPU sealants? Contact our sales team for a tailored quotation, sample request, or technical documentation. We support distributors, OEM partners, and project buyers worldwide with flexible logistics and packaging options.
