Pretreatment: The adherent surfaces have to be clean, free from fat, dry and sustainable.
All adherent surfaces must be clean and any contaminant such as release agents, preserving agents,
grease, oil, dust, water, old adhesives or sealants and other substances which could affect adhesion,
should be removed. Cleaning of non-porous substrates: Apply OTTO Cleaner T (airing time approx. 1
minute) using a clean, lint-free cotton cloth. Cleaning porous substrates: Clean surfaces with steel-wire
brush e. g. or a grinding disk to remove loose particles.

Primer Table: The demands on elastic sealings and bondings depend on the respective exterior influences. Extreme
fluctuations in temperature, tensile or shear forces, repeated contact with water etc. demand high
requirements of a bonding. In such cases it is advisable to apply primer according to the
recommendations of our technical department (e. g. +/OTTO Primer 1216) in order to achieve a resilient
bonding.

Application information: Due to the many possible influences during and after application, the customer always has to carry out
trials first.
Please observe the recommended shelf life which is printed on the packaging.
We recommend to store our products in unopened original packagings dry (< 60 % RH) at
temperatures of +15 °C up to +25 °C. If the products are stored and / or transported at higher
temperatures / air humidity for longer periods (some weeks), a diminuition of durability or a change of
material characteristics may arise.
