Product Information

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. 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. D3 adhesives are often referred to as “water resistant” and D4 adhesives are referred to as “waterproof”. Whilst this gives a simple way of identifying the difference, it is not strictly true to say that D4 is “waterproof”. The official description of the durability classes from the EN204 standard is shown below and this gives context around what you can expect the bond performance to achieve. However, if you can't find what you need please call us 01422 315300 and our Sales Team will be happy to help. 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.

Provides the user with a waterproof D4 grade wood adhesive with none of the safety issues associated with conventional isocyanate containing (polyurethane) D4 grades.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:

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. DESCRIPTION OF DURABILITY CLASSES D4: Bespoke furniture. High quality joinery, including windows, doors etc. in extreme situations. Timber frame applications including the bonding of chipboard flooring. Bond It offer a wide range of high quality building products for both the Trade and DIY enthusiasts. Covering everything from silicone sealants to bitumen roofing solutions we have it covered. Split into easy identifiable, recognised brands finding the right product for the right job should be easy. 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”. 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.One adhesive does all - our D4 Glue saves time and money for the installation of chipboard flooring. 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. D2 = Interior with occasional short-term exposure to running or condensed water and/or to occasional high humidity provided the moisture content of the wood does not exceed 18%.
