EVO-STIK GRIPFILL Gap Filling Adhesive, Bonds almost any surface, Colour: Buff, 350ml

Product Information

Bergquist Brand Liquid Gap Fillers are expertly engineered, thermally-conductive gap filling liquid materials designed to enable dispensing application for high volume manufacturing operations. The materials provide excellent thermal and mechanical performance, while inducing virtually zero stress on components during assembly. Because they are liquid mediums, thermal gap filler materials can conform to highly intricate topographies and multi-level surfaces, delivering better wet-out for optimized thermal resistance that is generally lower than more solid pad-based mediums. Application volume and pattern is completely adaptable. Gorilla Heavy Duty Grab Adhesive has an open working time of up to 10 minutes, which allows more flexibility when finding the right position. Single component, polyurethane adhesives are what we will be focusing on in this blog. 2. Two-part polyurethane adhesives Polyurethane adhesives contain isocyanates which may cause occupational asthma and are a suspected carcinogen. Handling times for polyurethane foaming adhesives can range from as little as 5 minutes to 30 minutes. Slower set time adhesives are beneficial when more time is required to position clamps and assemble complicated joints.

Adiseal is a versatile and high-performance product that can successfully bond a wide variety of materials, including:Image illustrating the open cell structure of Polyurethane glue (left) compared to the solid form of Wood Max Express Extremely versatile as able to make bonds with a wide range of building materials, including all types of wood, metal, and masonry. Some adhesives require activation by either moisture, activator, or in the case of anaerobic adhesives – the activator is the metal surface itself. With these adhesive technologies, the maximum gap fill refers to the distance or depth that the adhesive will cure through if the activator is on one surface. However, for additional cure depth or gap fill, activate both surfaces. Maximum Gap Fill for Optimum Bond Strength vs Maximum Gap Fill for Potting For UV and Visible Light Cure Adhesives the maximum gap fill for maximum shear strength may be listed. But the actual maximum gap fill capabilities depend upon the adhesive formulation, as well as the intensity and wavelength of the light. Low intensity UV light will allow a large cure depth. For example, a 5 gallon pail of some UV adhesives will cure through to the bottom of the pail if left in the sun for a day or two. Very high intensity light will cure through a much shorter distance (generally less than an inch). The incredible bonding power of Wood Max Express is approximately 4x greater than the strongest grab adhesive and effectively joins two pieces of wood to form a single, solid timber component. It can also be used to bond wood to metals, masonry, and other building materials. Advantages of Wood Max Express vs Polyurethane Glue

To clean surface while adhesive is still wet/uncured, wipe wet adhesive off the project immediately with a dry cloth. Isopropyl alcohol (IPA) may be used according to manufacturer’s instructions. For cured/dried adhesive, mechanical means such as sanding or scraping are necessary.

If needed, use clamps, tapes, or other means to hold the surfaces in place while the adhesive cures. Hand tight in just 30 minutes. Full bond strength is achieved after just 8 hours compared to the usual 24 hours with PU. Maximum Gap Fill of the adhesive is often stated on the technical data sheet, but what does it mean? The Maximum Gap Fill of an adhesive may be related to:

Fans of PU glue can also be its biggest critic, especially when it comes to cleaning up. That is when revolutionary products like Wood Max Express can fill the void – literally! There is no doubt that foaming PU glues are superb, their popularity in the joinery and construction industry is testament to it. In the world of adhesives, polymer technology is always improving, and that ongoing development allows manufacturers to design new products and alternatives which give even stronger bonds and are safer to use. Often adhesive specialists will use the term gap fill to refer to how tall the adhesive will stand up. In other words, what viscosity will prevent it from running out of the joint? A very thin adhesive will flow out of a large gap. But a higher viscosity adhesive with the appropriate rheology will stay in place.month shelf life. Polyurethanes can have a shelf life as little as 9 months, in fact it is not uncommon for them to part cure within the container. The long shelf life of Wood Max Express prevents waste and therefore saves money. Wipe off as much adhesive as possible with a dry cloth. When the majority of the adhesive has been removed, wash skin thoroughly with soap and warm water.

Wood Max Express is a revolutionary adhesive based on SMP polymers. I must stress, it is important not to confuse this formulation with hybrid polymers such as Sumogrip, CT1 and EB25 which are high strength grab adhesives. Hybrid polymer-based grab adhesives are used for ‘attaching’ one product to another, such as when fixing skirtings and trim. Due to crosslinking during the curing process, polyurethane adhesives form waterproof bonds to EN 204 D4 standards, making them ideal for external applications. Single component moisture cure adhesives like Permabond MS Polymers may list cure in mm/ hours. In other words the adhesive will cure 5mm deep every 24 hours. Depending on the joint design the adhesive can reach a point in which the cured adhesive cuts off the supply of moisture. And thus shuts off the cure mechanism. Viscosity

Advantages of Wood Max Express vs Polyurethane Glue

Their exceptional resistance to chemicals is a benefit in nearly all cases, but it makes clean up very difficult – especially if the product leaks on to surrounding materials caused by the foaming nature of the glue. Single component, foaming adhesives do not require any resins or hardeners to be added to them. They work by themselves Completely waterproof to EN 204 D4 standards. Particularly suitable for external joinery applications. Single part foaming polyurethanes are versatile and durable adhesives, offering fast bonding with high strength. They are easy to apply and can give excellent results providing clamping and substrate compatibility are considered.
