SEMFORITE® - A powdered resin glue ideal for use in all joinery and lamination work - - Accommodates differential movement/flexing, e.g. in coachwork, saddlery, etc. - - Excellent performance in all marine and outdoor applications.  Also available in 12.5kg and 25kg pack s   -
Product Description Semforite is an easy-to-use, powder adhesive that is mixed with water and applied as a standard adhesive. Unlike PVA and water-based glue, the chemical composition is changed by the addition of water to form an irreversible resin (resists chemical attack). The adhesive dries clear with no discoloration or shrinkage.
Applications This adhesive is ideal for all manufactured and composite timber including plywood/laminated boarding, particle boarding, MDF, HDF, veneering, either by hot or cold pressing, solid wood flooring etc, and for all internal and external joinery work - from cabinet-making to boat-building.
Timber Preparation The preparation requirements are identical to other wood glues - ideally the moisture content should be below 12%. The wood surfaces should be flat and smooth, with all knots stopped and no contamination from oil or other materials, etc.
Manual Mixing Dissolve the resin powder using a ratio of between 50:100 and 70:100, water:powder by weight. Pour about 2/3 of the required water into a suitable pot or container using a table knife or mixing stick (avoid using spoons - they clog). Add the powder and gently stir the mixture until a uniform paste is achieved (making sure there is no clumping at the bottom of the container) then stir in the remaining water.
Mechanical Mixing Dissolve the resin powder using a ratio of approx 60:100, water:powder by weight. Pour about 2/3 of the required water into the mixer and switch on the mixer. Add all the powder gently into the running mixer. When a consistent solution is achieved, add the remaining water.
Working Time Typical working time of the mixed glue is 1 hour at 20°C  and 2 hours at 15°C. Mixers, reusable containers and utensils should be cleaned with warm water as soon as the mix begins to lose fluidity. Keep joints under pressure or clamped until the glue has set (approx. 4 hours at  20°C ).
Storage The powdered resin should be stored in a cool, dry place. Care should be taken that the powder does not absorb moisture and water, in order to avoid agglomeration and deterioration. In ideal conditions, the shelf life should be several years but it is worth noting that one of the main causes of deterioration in powdered products is condensation within the packaging - so all packs or containers should be stored at a constant temperature, away from outside walls and off concrete ground floors, etc.
Handling & Transport This product is non-hazardous. The small amount of free formaldehyde in the powder may cause minor irritation if in contact with very sensitive skin. Hands should be washed with soap and hot water after the working day. A dust mask should be worn when emptying bags, etc. A suction hood is needed during hot press and in any large scale mixing, draughty conditions etc. The material should be kept dry and out of direct sunlight during transportation.
Performance Standards This product may be used internally or externally and is water-resistant to at least BS EN204 D3 (test methods BS EN205 2016) and also conforms to BS EN301 2023 A3 (test method BS EN302-1 2023) and water-resistant when tested against DIN Spec. 68602/3 Section B3.
How Much Powder? As an illustration, it takes about half-a-cup of water for each cup of the loosened powder to make a little over one full cup of glue, and a kilo of powder will make around 1.5 litres of glue paste, but dilution can be varied to suit the application, type of timber, etc. For consistent results - and because of possible settlement of the powder during storage - water and powder should be weighed out each time. 
Delivery & Packaging  We may use alternative packaging to the container for the 3kg/5kg amounts illustrated, both to avoid damage in transit and to ensure that the package will pass through a standard letter box if sent by post, etc., but packages are always double-sealed in polythene and completely waterproof. We are phasing out the 220g designation and dispatching 250g packs instead, at the same price. Keywords: UF resin, urea formaldehyde, wood, timber, glue, adhesive, waterproof
