Insulating Glass Silicone FF9338

硅酮中空玻璃密封胶 FF9338
Insulating Glass Silicone FF9338

Two-part neutral-cure silicone for the secondary seal of insulating glass: high modulus and low gas permeability — this is what decides whether the cavity still holds its gas ten years on. Mixed A and B give a working life of at least 20 minutes, 48 HSA hardness and 85% elastic recovery, suited to in-line factory gunning.
