• 對混凝土、砌築砂漿和牆板提供優異的粘結性能
• 不含氯化物，安全環保

典型用途

• 與水泥混合作為混凝土表面改性劑，促進抹灰、砂漿和地坪找平層的粘結
• 作為鋼筋保護層的保護漿
• 提高砂漿和撒沙仔的粘結強度

webertec EVA is a high-performance ethylene vinyl acetate liquid admixture designed to be mixed with Ordinary Portland Cement (OPC) as a concrete surface modifier to enhance plastering and screeding. This polymer does not contain aromatic groups, preventing the risk of breakdown due to sunlight and heat, making it highly suitable for exterior use. It significantly enhances the adhesion strength of mortar and spatterdash.

Key Features

• Enhances adhesion strength of the cement surface
• Improves cohesion strength of mortar
• Provides excellent bonding to concrete, masonry, and panel walls
• Chloride-free, ensuring safety and environmental friendliness

Typical Usage

• Mix with cement as a concrete surface modifier to promote the adhesion of renders, plasters, and floor screeds
• As a protection slurry for steel reinforcement
• Enhances the adhesion strength of mortar and spatterdash
