Silicone Structural Sealant is a one-part, neutral cure, specifically designed for structural bonding and curtain wall adhesive construction applications. It easily extrudes in a wide rang weather condition and quickly cures at room temperature to form a high durable and flexible silicone rubber seal.
Structural Sealant has an excellent adhesive to most of construction material without a primer.
It has good features as follow:
a. Can be easily used and extruded any time.
b. Neutral cure-suitable for use on most construction materials.
c. Excellent adhesion to most construction materials without the primmer.
d. Excellent weather ability and stability.
e. High modulus after cured, extension/compression movement capability of up to ±25% of the original joint width.
Where to use
Silicone Structural Sealant is designed for use in structural glazing applications such as: use for structural adhesion and seal the joints of the structural glass and metal or other building components in the factory or building site. It is also be used to adhere stiffening elements to building panels and for other similar adhesive applications.
silicone structural sealant for construction is fit for structural usage. It should NOT be applied in the following conditns:
a. To all spaces that bleed oils, plasticizers or solvents such as wood immersed in oil, oil
Crack filler, and some uncured or sulfur zed fat, it should NOT be applied.
b. To the unventilated space (Silicone sealant need the water in the air to cure)
c. To the circumstances as immersed in water for a long time, underground all the year
d. To painted surfaces, may cause seal failure as the paint cracking or paint stripping
e. Frost or wet surfaces
f. Surface touch the food directly
g. Easily suffer mechanical clash
h. Fireproofing seal system
