Epoxy

By now, you already know that WVCO offers a wide variety of wood products solutions to the wood industry including patches, fillers, extenders, coatings, inks, abrasives, tapes, and a wide variety of outstanding application equipment and parts.

But how much do you really know about Willamette Valley Company (WVCO) products? One of the questions we often get is “What’s the difference between Synthetic Patch, Epoxy and Putty?”. Unique details about these products are outlined in this video, but keep reading for more info.

What is a Synthetic Patch?
Synthetic Patch is a two-component polyurethane that is dispensed through a metering system.

What does it do?
Synthetic Patch, often referred to as “patch” or “poly” repairs veneer voids, knot holes, splits, and cracks in plywood panels, MDO, HDO, laminated wood, and lumber. The polyurethane flows in and sets up in seconds to form a sandable patch that can be treated much like the wood it repairs. It can be nailed, screwed, painted, finished or overlayed. Patch comes in a variety of colors to compliment the wood being filled. Willamette Valley Company (WVCO) Synthetic Patch has passed the rigorous standards of the APA-Engineered Wood Association.

A great example of this product is WVCO’s CU-100 Synthetic Patch, designed and APA approved to fill and up-grade plywood panels, laminated beams, mouldings, door blanks and other wood products. It is a two-component ambient temperature cured polyurethane resin system that is mixed and applied using WVCO’s dispensing and meter equipment.

What is Epoxy?
Epoxy is a two-component product, hardener and resin, that is mixed on-ratio either by hand or through a metering system. WVCO Epoxies come in a variety of set times and in one-to-one and two-to-one ratios.

An example of one of our Epoxies is E-100 Epoxy, an ultra-clear, high-gloss finish, faster set epoxy. This easy-to-use, 1:1 mix ratio is ideal for house hold and craft projects. For industrial or large projects it is best applied using WVCO metering system. It is versatile enough to be used on most surfaces: especially wood either smooth or rough, stained or painted. E-100 forms a thick, durable, high gloss, clear finish for tables, clocks, game boards and furniture.

What does it do?
Epoxy creates a tough repair that bonds tenaciously to the wood in large voids and knotholes in lumber, laminated beams, siding, molding, and plywood. Once cured, the epoxy can be treated just like wood: sawed, nailed, screwed, sanded, painted or stained. Epoxies are produced in various wood colors. WVCO Epoxy’s have passed the rigorous standards of the APA-Engineered Wood Association.

What is Putty?
WVCO Wood Putties are water-based pliable putties that can be hand or machine applied. They are designed for softwoods, hardwoods, and particleboard edge filling. WVCO Putties are used by cabinetmakers and on large production lines to fill core voids, larger holes, and splits in wood. The putties come in a variety of colors to blend with the woods being filled. Putty is easily sanded, is stainable, and takes a finish. WVCO Wood Putties have passed the industry standards of the APA-Engineered Wood Association.

WVCO’s Famowood is a good example of a putty. Famowood S/F FTS Birch is an acrylic-based wood filler used to repair defects in all types of wood. This product is supplied to the customer in a ready to use form and is formulated to be smoothly applied with a flexible putty knife or automated system. Once dried, it can be easily sanded, stained or painted.
