Product Introduction
Natural rubber primer R129FA/B is specifically designed for the pretreatment of difficult-to-bond elastomers such as vulcanized rubber and thermoplastic rubber (TPR), delivering stable treatment results and durable bonds. Its core strength lies in efficiently activating the substrate surface and promoting adhesion-transforming inherently inert, hard-to-bond surfaces into a state that is optimally ready for adhesive application. This ensures bonding quality and long-term stability of assembled components, reducing the risk of failure.
When using natural rubber primer R129FA/B, additive B powder must be added. This serves multiple purposes: it adjusts the viscosity of the primer for smoother, more uniform application; increases the crosslinking density of the cured treatment layer for a more stable structure; and enhances the chemical resistance and thermal stability of the treatment layer, thereby improving ultimate bond strength and making the bonding results more reliable.
Natural rubber primer R129FA/B is especially suitable for demanding bonding applications such as sole bonding, precision rubber component assembly, automotive parts manufacturing, and sports equipment production. Its specially optimized formulation effectively prevents bond failure, improves the adhesive layer's resistance to dynamic stress and harsh environmental conditions, and extends the service life of finished products such as rubber outsoles.
As a well-recognized rubber primer, it simplifies production processes by eliminating time‑consuming and labor‑intensive sanding steps-saving both manpower and time. Whether for rubber-to-rubber bonding or complex assemblies involving rubber and other materials, it delivers stable, high-strength adhesion. For high-end manufacturing scenarios where both production efficiency and product quality are essential, this primer is particularly reliable. You can trust it for pretreatment with complete confidence.

Product Feature and Application
- Add B powder to R129FA according to the specified ratio (for white or light-colored rubber, add 1–1.5% B powder to R129FA; for black or dark-colored rubber, use 1.5–3%). Ensure complete dissolution and homogeneous mixing.
- After cleaning the shoe material surface, apply this primer evenly using a brush or cloth.
- Drying time: Dry in an oven at 55±5°C for 2–4 minutes before applying adhesive. Apply the adhesive evenly and completely, avoiding insufficient coverage or excessive buildup.
- Avoid using metal containers. Use only plastic or ceramic containers for storage and handling.
Precautions
Conduct a prior test before full-scale application.
Keep this chemical product away from children, fire, and moisture.
