TrafficGuard LS

Two Component Elastomeric Loop Sealant

TrafficGuard LS – Two Component Elastomeric Loop Sealant. TrafficGuard LS is used for sealing loops and other embedded wire detection systems in concrete or asphalt pavement. It is designed to provide durable, flexible, and chemical-resistant joint seals, especially in traffic-bearing surfaces.

 This is a two-component elastomeric sealant system. It consists of a base component and a hardener, which are mixed before application.

 Used primarily for roadway, airport, or industrial paving applications involving embedded sensors or wire loops. Suitable for environments exposed to automotive fluids, fuels, and various industrial chemicals.

·      Pot Life & Cure: Not explicitly provided in this sheet. Usually determined by the base and hardener reaction, and varies with ambient conditions.

·      Temperature & Humidity Limits: Not listed, but as with most elastomeric sealants, avoid application under high humidity or at surface temperatures below 5°C or above 35°C unless otherwise specified by the manufacturer.

·      Chemical Resistance:

o   Excellent resistance to acids (e.g., hydrochloric, phosphoric, lactic), fuels (diesel, gasoline, MTBE blends), alcohols, and solvents including acetone and toluene.

o   Marginal or conditional performance against methylene chloride and MTBE (marked as C – conditional, wash down within 1 hour).

o   Not recommended for sulfuric acid at concentrations above 30%.

·      Film Durability: Rated 8–10 on the 72-hour spot test against common aggressive chemicals like brake fluid, anti-freeze, and acids, indicating very good to excellent film retention.

·      Discoloration Notes: Exposure to HI (Hydroiodic acid) may cause iodine discoloration.

·      Thickness: The TDS refers to 16 mil film application in chemical resistance testing, suggesting this is a typical applied film thickness.

·      Designed for professional use only.

·      Exhibits excellent resistance under 21-day immersion conditions in accordance with ASTM D3912.

·      Results rated as R (Recommended), RC (Recommended with Conditions), or C (Conditional – requires wash down), aiding in material selection for chemically aggressive environments.

·      For best performance, confirm compatibility with local conditions and consider consulting ChemCo Systems for site-specific application support.
