JOINTFILL 302 Flexible Control Joint Filler

Basic Use: Jointfill 302 is a two-component epoxy joint filler designed to be used in control and construction joints in concrete industrial floors. Jointfill 302 is a low modulus, flexible joint filler used in saw cut floor joints to provide support and load-bearing capacity at the joint edges. Jointfill 302 is used in floor control joints where slight movement is possible due to thermal variations. It is available in two consistencies, self-leveling and gel, for horizontal and vertical applications. Typical Applications: Control and construction joints in industrial concrete floors; repair compound to seal and fill random cracking in floors; joints in penitentiaries where a tamper-proof and gouge-resistant sealant is required. Limitations: Do not use outside or as an expansion/ contraction sealant. New concrete slabs must be at least 3 months old before installing Jointfill 302, according to ACI 302. Composition: Jointfill 302 is a two-component, moisture insensitive, 100% solids epoxy joint filler and sealant. Applicable Standards: ACI 302, Guide for Concrete Floor and Slab Construction, Section 4.10, Joint Materials. We have other products and systems of which we can Engineer to fit your application.

FAQs ABout Our PC-517 Poly-Chemcure Coating

PC-517 Poly-Chemcure Coating is designed for a variety of surfaces, including steel, concrete, and other industrial substrates. It is particularly effective for protecting steel tanks, pipelines, and structural components exposed to corrosive environments. The coating adheres well to properly prepared surfaces, ensuring optimal performance and durability.

The recommended application process for PC-517 Poly-Chemcure Coating involves thorough surface preparation to remove contaminants like rust, grease, or old coatings, typically through abrasive blasting for optimal adhesion. Once the surface is clean and dry, the coating components should be mixed according to the manufacturer’s instructions until a uniform consistency is achieved. The coating can be applied using a brush, roller, or spray equipment, depending on the project requirements and surface type. Multiple coats may be necessary for enhanced protection, with proper curing time allowed between layers to ensure durability and performance.

PC-517 offers exceptional resistance to a wide range of chemicals, including acids, alkalis, and solvents. It is also highly resistant to abrasions, making it suitable for areas subject to mechanical wear. Its robust formulation protects against environmental factors such as UV radiation, moisture, and temperature fluctuations, ensuring long-lasting performance in harsh conditions.

The typical curing time for PC-517 varies depending on temperature, humidity, and coating thickness. Under standard conditions (approximately 25°C/77°F and low humidity), the coating may cure within 24–48 hours. Full curing for maximum chemical and abrasion resistance usually takes 7–10 days. Factors like lower temperatures, higher humidity, or inadequate ventilation can extend curing time.

Yes, PC-517 is engineered to perform well in high-temperature environments and extreme conditions. Its heat-resistant formulation ensures stability and adhesion in temperatures up to its specified limits. Additionally, it withstands harsh industrial settings, including exposure to aggressive chemicals, mechanical impacts, and fluctuating environmental conditions, making it a reliable choice for demanding applications.
