Eposeal 300 EPOXY BINDING PRIMER ¬ Excellent penetration of porous surfaces ¬ Ideal sealer coat before solvent-free epoxies ¬ Long pot life and easy application INTRODUCTION Eposeal 300 is a solvent-based, low viscosity epoxy sealer. It has been developed primarily for use on wood but can also be used on other materials such as GRP stone, ferrocement, brick, etc. Eposeal 300 has an extremely low , viscosity which ensures that the product achieves rapid and deep penetration of porous surfaces. Once Eposeal 300 material has soaked into a surface, the adhesive nature of the epoxy base will help to consolidate and strengthen that surface. The resultant epoxy sealing layer provides a high adhesion and moisture resistant base for any type of paint, varnish or epoxy coating system. For example, many woodworking applications combine the penetrating power of the Eposeal 300, with the thick, clear coating capability of SP 320 to produce a strong, highly protective, deep gloss surface on wood. The solvents used in Eposeal 300 evaporate quickly once the product is brushed out, so that subsequent layers of Eposeal 300 can be applied in quick succession. Providing the lid is replaced on the mixing pot, the long pot life of Eposeal 300 means that just one mix can be used for multiple coats.

INSTRUCTIONS FOR USE WORKSHOP CONDITIONS For optimum results Eposeal 300 should be used at between 10 - 25°C. It can be used at lower temperatures but the cure will be slower. As the relative humidity (RH) can affect coating quality it is important to ensure that the RH is below 70% in order to avoid surface blooming. The room should be well ventilated to aid solvent release. PIGMENTING Eposeal 300 is not suitable for use with Gurit epoxy pigments but polyester type pigment colours may be used. WOOD STAINING SURFACE PREPARATION All surfaces should be clean, dry and dust-free. Prior to...

HEALTH AND SAFETY The following points must be considered: 1. Skin contact must be avoided by wearing protective gloves. Gurit recommends the use of disposable nitrile gloves for most applications. The use of barrier creams is not recommended, but to preserve skin condition a moisturising cream should be used after washing. 2. Overalls or other protective clothing should be worn when mixing, laminating or sanding. Contaminated work clothes should be thoroughly cleaned before re-use. 3. Eye protection should be worn if there is a risk of resin, hardener, solvent or dust entering the eyes. If...

TRANSPORT & STORAGE The resin and hardener should be kept in securely closed containers during transport and storage. Any accidental spillage should be soaked up with sand, sawdust, cotton waste or any other absorbent material. The area should then be washed clean (see appropriate Safety Data Sheet). Adequate long term storage conditions for both materials will result in a shelf life of two years for both the resin and hardener. Storage should be in a warm dry place out of direct sunlight and protected from frost. The temperature should be between 10°C and 25°C. Containers should be firmly...
