Polyfix Rapid GP Glue (HV) Instant Glue for Strong and Fast Bonds. This strong and long-lasting glue dries quickly, usually in about 10-15 minutes. It sticks well to different surfaces in various industries, but it’s mainly used for indoor jobs. You can use it to stick things like PVC, charcoal, acrylic, and Mica sheets onto PVC/WPC foam boards, MDF, HDHMR, Gypsum, Particle, and PLYWOOD boards. You don’t need to use masking tapes when you use this glue. It’s also good for jobs where there are small gaps between surfaces, like sticking metal strips onto wooden, WPC, or PVC boards. The glue is thick and won’t drip or run, so it’s great for jobs where you need to stick things vertically. To use it, just put the glue on one surface, then line up and press the second surface onto it. Hold it in place with your hand for a few minutes, and it will stick well.
