Natural Rubbers

Natural rubbers are typically processed into latices or modified derivatives that appear as milky white liquids or viscous solutions. Their functionality involves providing flexibility, elasticity, and impact resistance to coating films. Key features include excellent elongation, good adhesion to various substrates, and sound damping properties. They are highly suitable for flexible coatings, sealants, and elastomeric roof coatings, where their ability to accommodate substrate movement and provide tough, resilient films is critical for long-term performance. 

Synthetic rubbers like SBR or acrylic emulsions are common alternatives, but natural rubber derivatives offer a renewable resource option with inherent elasticity. Sub-types often involve different grades of natural rubber latex, or chemically modified versions designed to improve specific properties like UV resistance or adhesion.
