Sikalastic®-610 R IN
Single-component, moisture-cured pure polyurethane liquid roof membrane
Product Overview
Sikalastic®-610 R IN is a single-component, cold-applied, moisture-cured liquid membrane based on aromatic pure polyurethane. Applied straight from the container by brush or roller, it cures with atmospheric moisture into a seamless, elastic and highly durable waterproof film with a high solids content for excellent build per coat. The membrane is water, frost and root resistant, retains crack-bridging even at lower temperatures and remains vapour permeable, making it a strong choice for high-performance roofs, balconies and terraces with bonded tiles, and green roofs or planters. It bonds to a variety of substrates, offers a wide service temperature range and is easy to repair and maintain. Space Arc Engineering, an authorized Sika distributor in India, supplies Sikalastic®-610 R IN for premium roof waterproofing and landscaped-roof projects.
