PAINTING INSTRUCTIONS (Contd)
WARNING
Wear neoprene gloves and eye protection when mixing or coating
KS 55. Skin irritation or eye damage may occur if procedure is
performed without neoprene gloves or eye protection.
Ensure proper ventilation and wear a respirator apparatus when
working with KS 55. Injury to personnel may occur if used in a
confined area.
Wash hands and wrists with skin protectant and rub with skin
protectant ointment before and after performing task. Skin
irritation may occur if hands and wrists are not properly cleaned
and protected.
PNOTE
Ensure area to be coated is dry.
Coat bridge in a temperature range of 6475F (1824C)
Coat roadway within eight hours of cleaning. If the area shows any
contamination, perform a follow-up treatment in compliance with
E 02 005 0803.
Pre-heat the area to be coated to a temperature range of 6877F
(2025C).
To adapt the repaired spot to existing coating, apply a second coat
of KS 55 to the wet first coat.
3.
Apply KS 55 with a brush to damaged area.
4.
Apply corundum mixture per task a, steps 3 through 5.
5.
Allow parts to dry and store per task a, steps 6 and 7.
SURFACE TREATMENT WITH METAL SEPARATING AGENT
a. Preparation of Mixing Components.
NOTE
To ensure proper bonding, joint flanks or bonded surfaces must be
dry, clean, free of dust and grease.
1.
Clean per aluminum cleaning specification E 02 005 0803.
CAUTION
An excess dosing of hardener (max 10:1 by volume) does not cause
a deterioration of the material properties. However, under-dosing of
the hardener will cause a deterioration of the hardener and must
be avoided in every case. A deterioration of the hardener may cause
damage to equipment. When preparing mixture with automatic
mixer, ensure correct setting of the dosing cylinders.
2.
Mix components in proportion of 10:1 by volume. Use two-component mixture within approximately
30 minutes (pot time at 75F (23C)).
CAUTION
To avoid metal separating agent failure, do not process GD 677
under 50F (10C).
NOTE
Pot time is shorter at higher temperatures. As a general rule, cut
time in approximately half for every increase of ten degrees celsius:
30 min pot time at 68F (20C).
15 min pot time at 86F (30C).
8 min pot time at 104F (40C).
3.
Mix only the quantity to be processed in this time.
