K-Fix Construction Chemicals the retail arm of Chembond — manufacturers and distributors of construction chemicals in India — has introduced KEM PROOF 86 and KEM PROOF 87, elastomeric waterproof exterior coatings aimed at external walls and roof protection respectively.
KEM PROOF 86 is capable of resisting movements in structures and has crack bridging and water proofing properties due to its good film thickness. It has elasticity (<100% at 100 – 125 microns DFT) and can withstand heavy rains. It has longer service life due to good UV resistance, is resistant to fungus and algal growth and has good breathability and permeability to water vapour. It is a non-toxic coating with low dirt pick up due to low tack-free time. The coating is ready to use and easy to apply using brush roller and spray. It ensures desired thickness as there is no need for additional water for dilution.
The KEM PROOF 87 is an elastomeric coating based on selected acrylic co-polymers. When applied, it cures to form a durable, protective, waterproof membrane. It is applied by brush or roller. It can be applied on concrete, cement board, wood, brick, stone and tiles. It is a single-component emulsion containing inert pigments and has a brushable consistency. It has good resistance to UV and atmospheric gases and salts ensure durability. Its tensile strength and elongation ensures crack bridging and movement accommodation and it is highly resistant to water.
