WEST SYSTEM 105 is the resin component of a two-part epoxy system. It needs a compatible hardener selected for the job. Ask PLC Marine about the combination for your repair, laminating or coating project and request a quotation in Mexico.

Select for your project
205 or 206: choose for the working conditions
205 Fast is intended for a faster cure and lower working temperatures. 206 Slow provides more application time. Share the expected temperature, job size and application method to select the combination; the product name alone is not enough.
207 or 209: clarity and working time are different decisions
207 Special Clear suits applications where a transparent finish matters, such as visible wood. Sun-exposed work still needs a suitable UV-protective finish. 209 Extra Slow extends working time, particularly in warm conditions; it does not replace 207 as the choice for a clear finish.
Define what your order should include
Tell us whether you are bonding, wetting out cloth, filling or coating. Include the material, area or volume and photographs. Resin, hardener, fillers and metering pumps can be specified as separate quotation items; pricing, container sizes and delivery are confirmed when quoted.
Frequently asked questions
Do all hardeners use the same mix ratio?
No. 205 and 206 use 5:1 by volume; 207 and 209 use 3:1 by volume. Do not apply these figures directly to weight. Check the label, combination-specific data sheet and metering equipment before mixing.
Do metering pumps mean a 1:1 mix?
No. One full stroke from each correctly calibrated pump dispenses different quantities to achieve the required ratio. Use the pump matched to your hardener and follow its instructions.
Is this sold as a complete kit?
This page describes the system, not a fixed-content kit. Ask for the quotation to itemize its components and quantities, particularly if you already have resin or hardener.
