Which VELCRO® Brand adhesive is the strongest?

While there isn’t a sliding scale with the VELCRO® Brand adhesives there are some that are ‘stickier’ than others. The PS14, PS15, PS30 and PS51/52 are all rubber-based adhesives suitable for most surfaces, hard plastics, wood, painted walls and UPVC (window frames to name a few. These are all similar types of adhesives, but they have different properties, for example, the PS15 and PS30 have the best tack of all the adhesives, so are ideal for when you need to apply the tape in a hurry. The PS51/52 adhesive is applied to the back of the VELCRO® Brand Heavy-Duty tape in a thicker layer, so is great for un-even surfaces. The PS18 is a water-based acrylic adhesive which will stick to most surfaces but is most suited for any materials containing plasticisers, usually these are PVC and vinyl. The rubber-based adhesives are not suited to these materials, the PS18 isn’t necessarily stronger than the PS14, it’s just suited to different materials and applications. With all that said, to the achieve the strongest bond the choice of adhesive will depend on your application, for example the PS15 is the strongest on polypropylene and the PS18 is the strongest on PVC and vinyl, if you need any advice, please call us – 01373 827111
