Hardener in Paste

Hardener in Paste Ml.500

The paste hardener is an essential component when working with marble putty. It must be well mixed with the putty because it plays a crucial role in the polymerisation and catalysis process of the marble putty, which is why it is also called two-component marble putty. The hardener is based on peroxides, such as benzoyl peroxide, which reacts with the polyester resins in the putty, initiating the polymerisation process. During this chemical reaction, the putty is transformed into a solid, durable substance. This petrification process makes the mastic suitable for bonding or grouting materials such as marble, stone or granite. In other words, the hardener is essential to ensure that the mastic achieves the right consistency and durability needed to perform its task of fixing or sealing these surfaces. It is important to carefully follow the manufacturer's instructions for the correct amount and mixing of mastic and hardener.
