RAKA Resin

Individual bottles of resin - click HERE for hardener

All Raka Epoxies are 100 % solids with no evaporating solvents and have low viscosity for superb penetration and wetting out of wood and fiberglass.

The Raka basic marine epoxy resin 127 is our standard resin with a low viscosity of 600 centipoise, very little smell and excellent wetting-out and clear-coating properties.

Our standard 2 to 1 mix hardeners are our slow hardener 606 and our fast hardener 610. All hardeners are designed to be mixed by volume. The fast hardener is very fast (pot life of a 3 oz. mass at 77 F is less than 8 minutes). Working cure strength for most applications, using fast hardener, is achieved in 6 to 12 hours at approx. 77 F.

The slow hardener is very slow (pot life of a 3 oz. mass at 77 F is more than 25 minutes). Working cure strength, using slow hardener, will take about 24 to 48 hours at approx. 77 F. 606 hardener should be used in temperatures above 60 F.

Our two to one mix ratio slow and fast hardeners are easy to use, are low blushing and can be mixed together to customize working characteristics and cure times.

RAKA boilerplate:

The basic epoxy ingredients we use come from the major chemical manufacturers. We blend and modify our epoxies to meet specific parameters to get the right balance of properties to suit our customers needs. We also add special additives that help to get the air bubbles out and to improve flow and leveling. These additives reduce surface cratering and pin holing that can be a result of a less than perfect substrate. Many epoxy sellers do not incorporate additives or additives of little effect.

Our epoxies have a proven track record showing excellent performance for marine and shop use. The strength characteristics, water resistance and the low viscosity of our products are excellent for working with wood and fiberglass. The majority of our business comes from our many satisfied repeat customers, many of whom build boats professionally. They have found that we give quality products and personal service at prices lower than even most discount stores. Give us a try and you'll agree!

RAKA Epoxy uses a mix ratio of 2:1 by volume, 43:100 by weight. Click HERE for a chart for mixing by weight.

About Hardener speeds:

The slow hardener is very slow (pot life of a 3 oz. mass at 77 F is more than 25 minutes). Working cure strength, using slow hardener, will take about 24 to 48 hours at approx. 77 F. Slow hardener should be used in temperatures above 60 F.

Our two to one mix ratio slow and fast hardeners are easy to use, are low blushing and can be mixed together to customize working characteristics and cure times.

Warmer temperatures will give better results, but by using our fast hardener it's possible to work in temperatures as low as 50 F. and get a hard cure. Full working strength will not be achieved though unless the epoxy has a period of at least 24 hours above 50 degrees.
