The Henkel 34989 LOCTITE® PC F720™ COLOR GUARD® Yellow Tough Rubber Coating – 3.78 Liter (Gallon) Can is a high-performance rubber coating engineered for industrial, aerospace, and MRO applications where reliability and surface protection are critical. Manufactured by Henkel / LOCTITE and identified by part number 338134, this product is trusted by professionals across aviation maintenance, manufacturing, and defense industries worldwide.

Available in a 3.78 Liter (Gallon) Can format and formulated in Yellow finish, this coating provides a robust protective barrier against environmental degradation, chemical attack, abrasion, and mechanical wear. Whether applied to metal substrates, composites, rubber components, or specialized aerospace alloys, it adheres tenaciously to properly prepared surfaces and maintains its integrity under demanding service conditions.

The formulation has been developed to meet strict performance and safety criteria applicable to aerospace and industrial environments. It delivers consistent coverage, excellent hiding power (where applicable), and a finish that resists cracking, peeling, and delamination over extended service life. Its resistance to common industrial chemicals, fuels, hydraulic fluids, and moisture makes it a preferred choice for critical surface protection applications.

Application is designed to be straightforward using spray, brush, or roller methods as appropriate for the product type and substrate. Surface preparation including cleaning, degreasing, and priming (where required) is essential to achieve maximum adhesion and performance. Always follow the manufacturer’s product data sheet (PDS) and safety data sheet (SDS) guidelines for mixing, application, and curing parameters.

The LOCTITE PC F720 in 3.78 Liter (Gallon) Can is an ideal choice for professionals who require a proven, specification-grade coating solution. Contact us for volume pricing, availability, and technical support to ensure this product meets your project’s specific requirements.
