Split into easy identifiable, recognised brands finding the right product for the right job should be easy. EVERBUILD D4 Wood Adhesive provides the user with a waterproof D4 grade wood adhesive with none of the safety issues associated with conventional D1 adhesives are the lowest in terms of durability. These adhesives work in interior areas in which the temperature rarely exceeds 50C. In addition, you can use them on wood with a moisture content up to 15%. They have a storage life of up to seven days in standard room temperatures and humidity. They have a required bond strength of less than 10 N/mm2, and you should use them for external wood bonding.

D4 Waterproof Wood Adhesive - Bond It
ThePfohl adhesive spreaderused in this videois the benchmark in the industry for applying adhesive to panels and boards. It is suitable for use with PVA and EVA water based adhesives and UF, MUF and PRF formaldehyderesins. Practically D1 and D2 are considered to be “interior grade” adhesives and should not be used anywhere where a high level of durability is required. If you are new to using PU adhesives, you may be wondering why they have a D in their title. You might be asking just how a D4 PU adhesive is any different to a D3 or D2 adhesive? It might be easy to tell a Tytex 1 kg 30 Min Set PU Adhesive from a Tytex 1 kg D4 PVA Adhesive. However, the D grade stands for durability and is part of the European standard BS EN 204 which governs the classification of wood glues for non-structural applications, and it helps to show how resistant the adhesive is to water. There are four durability gradings specified, so let us look at D1 through D4 adhesives. Durability Classes: D1 Adhesives: All PU adhesives which are single component MCPU adhesive are likely to conform to the D4 requirements by default as polyurethane is extremely tough and weather resistant.Litre Solvent Free External High Grade Industrial D4 Wood Adhesive Based on the latest hybrid resin technology. However, if you can't find what you need please call us 01422 315300 and our Sales Team will be happy to help. D3: High quality joinery, furniture making and veneering including flat panel lamination with plastic laminates. EVERBUILD® D4 Wood Adhesive is a solvent free industrial grade D4 wood adhesive based on the latest hybrid resin technology. EVERBUILD® D4 Wood Adhesive provides the user with a waterproof D4 grade wood adhesive with none of the safety issues associated with conventional isocyanate containing (polyurethane) D4 grades. low timber staining characteristics; no discolouration of the glue line due to the influence of process heat (eg. HF-press)

The next step up on the durability scale are D2 adhesives. Like D1 adhesives, you should only use D2 glues for indoor work. These adhesives can cope with occasional short term exposure to water or moisture and temporary high humidity. However, the moisture content of the wood must not exceed 18%. D2 has a seven-day shelf life in normal conditions and has a required bond strength of less than 10 N/mm2. If submerged in cold water for three hours and stored for a further seven days, however, D2 has a required bond strength of less than 8 N/mm2. D3 Adhesives D references of adhesives are commonly used to identify the water resistance of wood bonding adhesives, but strictly speaking they relate to the durability of the adhesive, not just the water resistance. The standard used to determine the durability class is EN 204: 2001 –“Classification of thermoplastic wood adhesives for non-structural applications”.To ensure safe storage of product, containers should be well sealed to prevent evaporation of water and the formation of skin on the surface. The emulsion must be stored at a temperature above freezing. A temperature of 15-23°C for not more than six months is recommended. Higher temperatures will affect quality and cause the formation of crusts and skins, especially if the containers are not tightly closed or subjected to direct sunlight for long periods. Provides the user with a waterproof D4 grade wood adhesive with none of the safety issues associated with conventional isocyanate containing (polyurethane) D4 grades.

Open assembly time is a maxiumum of 15 minutes depending on the materials to be bonded. Assembly times vary according to the moisture contents and porosity of the substrate and local conditions. Everbuild D4 Wood Adhesive can be used internally and externally and gives a high strength, water resistant, impact and temperature resistant bond D3 adhesives are considered to be water-resistant. You can use them in interior areas where there is frequent short term exposure to water or moisture and frequent high humidity. Unlike the previous grades of adhesives, you can use D3 outdoors in areas not exposed to the weather. In normal conditions, D3 has a seven-day shelf life with a required bond strength of less than 10 N/mm2. If stored in cold water for four days, it will have a required bond strength of less than 2 N/mm2. After a further seven days of storage, the required bond strength increases to less than 8 N/mm2. D4 Adhesives If the grade is classified as D3, then that means that it should have gone through the testing to ensure that it does meet the requirements, which give it its water reisistance. The full D3classifcation is set out in the EN 204 standard.If the grade is classified as D4, then that means that it should have gone through the testing to ensure that it does meet the requirements. The full D4 classifcation is set out in the EN 204 standard. Ideal for all general woodworking and joinery uses, assembly line work, RF HF cure systems, wood on wood laminating, furniture assembly and house hold DIY use. Another feature to look out for is the shelf life. D4 PVA is less stable than D1, D2, and D3 adhesives and most of them only have a recommended shelf life of 3 months. There are a handful, including Woodstikk D4 PVA,which have a shelf life of 6 months if stored correctly. If you require a fully “waterproof” adhesive for bonding wood, you will need to use a phenol resorcinol resin system, e.g. Prefere 4050, or a melamine urea resin system e.g. Prefere 4535.
