Sika SC-PS2 Two-component Polysulfide-based Construction Sealant
Made in Japan
Manufacturer: Sika
Model: SC-PS2
This two-component sealant cures through a chemical reaction between the main agent and hardener, and is a low modulus type with low tensile stress. After curing, it has excellent weatherability, design, and joint adhesion.
