The new line of adhesives and sealants

NEXTGEN low-modulus joint sealant based on hybrid polymers, Shore 25


Видео по продукту

One-component adhesive sealant KUDO® PROFF NEXTGEN is intended for creating flexible and high-strength sealing and bonding joints resistant to vibration and deformation. Used in the industrial and civil construction and renovation works for sealing and filling vertical and inclined expansion and compensation seams, facade and roof joints, cracks in building panels and roof constructions. Complies with ISO 11600 Type F Class 25 LM. Has excellent adhesion to most construction materials: stone, brick, concrete, glass, plasterboard, solid plastics (except polyethylene, polypropylene and fluoroplastic), ceramics, aluminium, metals, composite, stainless steel, wood. No priming is required. For indoor and outdoor works.

Hybrid adhesive sealant (modern analogue of MS-polymers) has high operating characteristics: forms a permanently elastic high-strength and durable joint; elastic for the whole service life; excellent for joining materials with different temperature expansion. Weather and temperature resistant. Thixotropic, does not flow or drip down the joint. After curing, it is possible to paint with aqueous and synthetic paints (in the case of solvent-based paints, run a test).

Chemically neutral, no chemical reaction with the materials to be bonded. Does not cause metal corrosion. Can be used for bonding delicate materials. Odourless, eco-friendly, non-toxic and non-flammable, free of isocyanates and solvents.


  • Resistant to UV, cleaning agents and detergents
  • Excellent adhesion to most construction materials with no primer
  • Wide operating temperature range: -40°C to +90°C
  • Can be painted over with almost all types of paints
  • Elastic and deformable for the whole service life
  • No shrinkage or bubbles formed

How to use

  • Recommended application temperature between +5°C and +35°C.
  • Apply the adhesive sealant to clean, degreased surfaces. For degreasing and cleaning, Silicone Remover KU-9100 is recommended.
  • Protect surfaces with masking tape to ensure an accurate application and remove it immediately after applying the adhesive.
  • For application, use a dispensing gun for sealants in foil packs.
  • Get the application gun ready: take the gun push-rod out until it stops, unscrew the nut and the nozzle, place the foil pack in the application gun. Carefully cut off the packaging left outside, close the gun, fixing the nozzle and the nut in the correct position: the cut packaging tip must fit into the nozzle. Cut off the nozzle diagonally (at an angle of 45°) to provide a suitable dosing hole.
  • Apply as a continuous roller, without gaps and overspreads.
  • Smooth down the sealant in the joint with a wet putty knife. A soap solution is very effective.
  • Remove cured sealant using mechanical methods.
  • Skin formation time is no less than 20 minutes, curing rate of 2-3 mm per day (at 23 °C and 50 % humidity).
  • Clean surfaces with uncured adhesive using solvent (acetone, white spirit).
  • Remove cured adhesive mechanically.

Warning! Do not use on surfaces where contact with food is possible. Not for joints that are permanently under water. If solvent-based paints are used, run a test.
