In the footwear and leather goods industry, if you want a bonded area to hold strong and last long, it all comes down to how well you do the surface preparation before applying the adhesive. Especially with materials like PU and oil leather-if the prep work isn't right, even the best glue won't help. Look at our PU shoe primer 135F. It was developed specifically to solve bonding problems on all kinds of difficult materials and help you get those tough bonds sorted out once and for all.

The advantages of PU Primer 135F are straightforward: good brushability-it feels right in your hand; strong penetration, so it gets deep into the material; and reliable surface activation that won't let you down. It's especially suited for materials like PU synthetic leather, oil leather, full-grain cowhide, and thick canvas-and it works particularly well on oiled or sanded leather surfaces. Its wetting ability is excellent, it enhances chemical bonding, penetrates deep enough, and creates a strong mechanical interlock effect. In plain English, it fundamentally improves the material's flexibility under bending, so it's less likely to crack or delaminate. It's a high-quality companion treatment for adhesives-with its help, your bonding results go up another level.

PU shoe primer 135F thoroughly cleans the substrate, evenly etches the material surface, removes invisible contaminants, and then forms a chemically active layer. This significantly boosts the final adhesive's bonding strength, durability, and weather resistance-so you're less likely to see delamination or aging. It's easy to apply, works with various production processes, and integrates smoothly into high-efficiency production lines. Whether you're assembling multiple materials or doing multi-layer lamination, it delivers consistent results without constant re-tuning.

Whether it's outsole bonding, material lamination, or producing fashion footwear, leather accessories, bags, or home decorations, 135F is an essential pretreatment step. By using this product, manufacturers can effectively prevent delamination issues, improve product durability, and increase yield rates-reducing waste from rework. PU shoe primer 135F also effectively stops bonded areas from peeling or cracking. It efficiently activates oily or coated surfaces, turning substrates that were once hard to bond into ideal surfaces for high-strength adhesive systems. Simply put, in the world of shoemaking adhesion, it's one of the most reliable solutions around-even in the most demanding applications, it helps you produce high-quality, high-performance finished goods.

1. Before use, add 5–10% hardener (R768) and mix thoroughly. The mixed primer is recommended to be used within 4 hours.
2. After cleaning the shoe material surface, apply this primer evenly with a brush.
3. Drying time: Dry in an oven at 55±5°C for 3–5 minutes or longer before applying adhesive.
4. Apply the adhesive evenly and completely, avoiding insufficient coverage or excessive buildup.
