Inside the brand

Solid adhesive, activated by heat.

Where k-System is the pressure-sensitive answer, k-Thermo is the heat answer — the same house, ALC Tecnologie Adesive in Venaria Reale, and the same solvent-free discipline, tuned for lines that already run a press or a laminator.

Four chemistries, two principal forms. EVA/PO, TPU, Co-PES and Co-PA — each made as adhesive film or adhesive web, with mesh and powder where the line scatters rather than lays. Instyle Overseas holds the range for Indian factories.

01The advantages

The advantages of k-Thermo systems.

Three reasons factories move a bonding step from solvent to heat.

01

Technological

k-Thermo products are designed by ALC engineers working closely with materials experts — every aspect of the adhesive application examined, from the chemical bond to technical compatibility.

02

Integrated

The result of an integrated approach: high quality and excellent service. The range adapts to a wide span of materials and industrial sectors — starting precisely with footwear and leather goods.

03

Eco-friendly

Highly performing, but extremely mindful of environmental impact: every solution is designed to minimise waste and harmful emissions.

04

Available in India

Instyle Overseas holds the k-Thermo range for Indian factories — samples, trial support, and production rolls landed with customs and inland transport handled.

02The adhesives

From Co-PA to Co-PES, through TPU and EVA.

For every need, the right adhesive is the right solution. Made as adhesive film, adhesive web, adhesive mesh or adhesive powder, each guarantees maximum performance for its bonding surface — and so an optimal result on the finished product.

1018F · 1116F · 1239W · …EVA / PO

Extremely versatile and economical, known for excellent adhesion on EVA foam and fabrics — widely used in footwear and leather goods, and one of the best-selling products on the market. Some formulations activate at particularly low temperatures, a real advantage on heat-sensitive materials. Polyethylene and polypropylene versions are made for industrial applications with higher melting points.

03Adhesive family

EVA / PO thermoadhesives.

Extremely versatile and economical, they are known for their excellent adhesion properties on EVA foam and fabrics.

Product code: 1018F, 1116F, 1239W, …
FilmWeb

Widely used in the footwear and leather goods industry, they represent one of the best-selling products on the market. Some formulations can be activated at particularly low temperatures, offering significant advantages in the processing of heat-sensitive materials — and for this reason they have a specific affinity with sensitive materials: leather, EVA, cotton, PES. Adhesives in polyethylene and polypropylene are also made for industrial applications, with higher melting points.

Melting range 72 °C – 145 °C.

Film or web — common to all four.

Every chemistry above is made in both forms. The form decides the character of the bond: film seals, web breathes.
