Fireproof sealant
DJ-A3-JS-701 fireproof sealant is a single component, neutral curing silicone sealant. DJ-A3-JS-701 product can produce superior adhesion to most building materials.
Product features
1. Easy to use: can be squeezed out for use at any time;
2. Excellent thixotropy and extrudability, which can be extruded at - 5 ℃ - 40 ℃;
3. Neutral curing: suitable for most building materials without adverse reactions or corrosive effects;
4. When encountering an open flame, it does not support combustion and extinguishes itself without fire;
5. After curing, maintain good elasticity under environmental conditions of -50 ℃ -150 ℃.
